Abstract: <P>PROBLEM TO BE SOLVED: To provide a display device in which the light emitting element can emit light at a constant luminance even when the current characteristic is changed by degradation or the like, which is fast in writing signals in pixels, which can display in gray scales accurately, and which can be reduced in size with a low cost, and also to provide a driving method thereof.  <P>SOLUTION: Each pixel of the display device has a current supply circuit, a switch portion, and a light emitting element. The light emitting element, the current supply circuit, and the switch portion are connected in series between a power supply reference line and a power supply line. The switch portion is switched between ON and OFF using a digital video signal. The amount of constant current flowing in the current supply circuit is determined by a control signal input from the outside of the pixel. When the switch portion is ON, a constant current determined by the current supply circuit flows in the light emitting element and light is emitted.  <P>COPYRIGHT: (C)2008,JPO&INPIT

IPC: H04R3/02
Filed: 2008-04-14
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the increase of noise by the phase shift of a filter to which signals gathered by a microphone are supplied.  <P>SOLUTION: The output signals of the microphone 1 are phase-inverted and supplied to a band-pass filter 3. The components of a band near both ends of the passing band of the filter 3 are taken out by band-pass filters 7 and 8. The output signals of the filters 3, 7 and 8 are added in a mixing circuit 6, and the output signals of the mixing circuit 6 are supplied through an amplifier 2 to a speaker 2. Since the sound waves of a phase opposite to the noise are radiated from the speaker 2, the sound waves of the speaker 2 and the noise at the position of the microphone 1 cancel each other. By the filters 7 and 8, the increase of the noise by the phase shift of the filter 3 is prevented.  <P>COPYRIGHT: (C)2010,JPO&INPIT
